1 Claim.

The present invention relates to new and useful improvements in conductor hangers and more particularly to hangers for suspending high voltage transmission line conductors.

An important object of this invention is to provide a conductor hanger which is free of all loose parts, such as nuts and bolts which are difficult to handle and assemble and which frequently become lost when removing the hanger and placing a conductor line therein.

A further object of the invention is to provide a conductor hanger which is automatically adjustable to accommodate conductors of various sizes and wherein the conductor is automatically gripped in the hanger by the weight of the conductor supported thereby.

A still further object is to provide a device of this character of simple and practical construction which is efiicient and reliable in operation, relatively inexpensive to manufacture, easy to install in position and which otherwise is well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view with parts broken away and shown in section;

Figure 2 is an end elevational view;

Figure 3 is a perspective View of one of the clamping dogs;

Figure 4 is a perspective view of the hanger arm, and

Figure 5 is a perspective view of the channeled conductor supporting shoe.

Referring now to the drawing in detail wherein for the purpose of illustration we have disclosed a, preferred embodiment of the invention, the numerals 5 and 6 designate a pair of side plates of substantially triangular shape and with aligned openings 1, 8 and 9 formed therein adjacent the corners of the plates.

A pair of clamping dogs I'll are formed with trunnions l l projecting outwardly from each side thereof, the trunnions of the respective dogs being pivoted in the openings 7 and 8 of the plates. The dogs ID are of irregular elongated shape and the trunnions II project from the sides thereof in an off-balance position to provide a lower end I 2 and an upper end l3 on the dog. The lower end I2 is channeled as shown at l4 and the upper end I3 is formed at one edge with a rounded heel l5.

An elongated shoe I6 is formed at one longitudinal edge with a channel I! and is curved downwardly at each end as shown at l8. An opening is extends transversely of the shoe at its intermediate portion to receive a pin 20 inserted in the opening 9 of the plates 5 and 6 to support the shoe between the lower edges of the plates. The pin 20 is removably secured in position by a transverse looking or cotter key 2|.

A hanger arm 22 is formed at its lower end with a semi-circular head 23 positioned between the plates 5 and 6 and extending upwardly therefrom. Trunnions 24 project outwardly from the opposite sides of the head 23 and extend into vertically extending slots 25 formed in the plates 5 and 5 adjacent the upper portion thereof. The lower surface of the head 23 is channeled as shown at 26 and the upper end of the arm 22 is bifurcated as shown at 2'! and formed with aligned openings 28 by means of which the hanger may be supported to a suitable overhead structure.

In the operation of the device, a transmission line or conductor 29 is seated in the channel I! of the shoe [6 and the conductor and shoe inserted upwardly between the lower ends of the plates 5 and 6 and secured in position by the pin 20.

The heels l5 of the dogs in ride against the rounded edges of the head 23 whereby the weight of the hanger supported on the arm 22 will cause an upward swinging movement of the upper ends l3 of the dogs and in downward swinging movement of the lower ends l2 thereof in gripping engagement with the conductor 29.

Likewise, a pulling action subjected to either end of the conductor will increase the gripping action of the lower ends of the dogs ID.

The slots 25 also enable conductors of different sizes to be seated in the channel I! of the shoe Hi.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully compreq hended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention what is claimed as new is:

A conductor hanger comprising a pair of spaced substantially triangular plates each having a lower corner and a pair of upper corners, a channeled shoe positioned between said plates, a pivot pin extending through the lower corners of said plates and through said channeled shoe intermediate its ends, further pivot pins extending through the upper corners of said plates, a pair of dogs positioned between said plates, each dog being eccentrically pivoted upon each of said further pivot pins, and an apertured hanger arm carried by said plates and between said dogs, said hanger arm including a semi-circular head at its lower end having a longitudinally extending channel at the bottom thereof, said plates including aligned vertically extending slots and said hanger arm including trunnions engageably received in said slots.
